Hi Renee, Lucas, and Viv!
I guess I don't know what little balloon things you are referring to?  Sorry...
 
Why does it get foggy at night?  Good question!  At about the same time every night 9:30ish pm there is a icy fog layer that slowly moves from about 150 meters overhead to eye level!!!  This is probably caused as the air temperature starts to decrease and the wind speed slowly decreases as well.  The combination of the two allows this cool moist layer to move closer to the surface of the snow!
 
See you soon
Craig
